springboot 使用redis实现session共享

1.pom依赖
<!-- redis -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>redis.clients</groupId>
                    <artifactId>jedis</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>io.lettuce</groupId>
                    <artifactId>lettuce-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>


 <!--session共享-->
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
            <version>2.1.12.RELEASE</version>
        </dependency>

2.properties配置
#redis
spring.redis.database=0
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=
spring.redis.timeout=30s
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.max-wait=-1s
spring.redis.lettuce.pool.min-idle=0
spring.redis.lettuce.shutdown-timeout=100ms
#session 共享
spring.session.store-type=redis

3.启动类加注解
@EnableRedisHttpSession//session共享
public class SpringbootApplication{
}

4.如果报错存入sess的User类无法序列化的话
User类加一个
implements Serializable
